well, you already know how to convert from mixed to improper, so let's simply do the multiplication, as it's very straightforward.


\bf 4\frac{2}{7}\cdot 2\frac{1}{5}\implies \cfrac{30}{7}\cdot \cfrac{11}{5}\implies \cfrac{30}{5}\cdot \cfrac{11}{7}\implies 6\cdot \cfrac{11}{7}\implies \cfrac{66}{7}\implies 9\frac{3}{7}

If f(x)=x^2 and g(x)=1/2x+3 find g(f(-1))
telo118 [61]

Answer:

1/5

Step-by-step explanation:

F(x)=x^2

g(x)=1/(2x+3)

g(f(-1))=?

x=-1→f(-1)=(-1)^2→f(-1)=1

g(f(-1))=g(1)=1/[2(1)+3]=1/(2+3)→g(f(-1))=1/5
